./configure时出现的问题：

checking for AALIB version >= 1.2.0... no
*** Could not run AALIB test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means AALIB was incorrectly installed

为何我已经安装了aalib和caca-devel这两个包，版本也可以，也能找到它们，怎么就不能用了呢？怎么就说我安装不正确呢？
